BROOKLINE BANCORP, INC. AND SUBSIDIARIES
Notes to Unaudited Consolidated Financial Statements (Continued)
In preparing these consolidated financial statements, management is required to make significant estimates and assumptions that affect the reported amounts of assets, liabilities, income, expenses and disclosure of contingent assets and liabilities. Actual results could differ from those estimates based upon changing conditions, including economic conditions and future events. Material estimates that are particularly susceptible to significant changes in the near-term include the

determination of the allowance for credit losses, the determination of fair market values of acquired assets and liabilities, including acquired loans, the review of goodwill and intangible assets for impairment and the review of deferred tax assets for valuation allowances.
The judgments used by management in applying these critical accounting policies may be affected by a further and prolonged deterioration in the economic environment, which may result in changes to future financial results. For example, subsequent evaluations of the loan and lease portfolio, in light of the factors then prevailing, may result in significant changes in the allowance for loan and lease losses in future periods, and the inability to collect outstanding principal may result in increased loan and lease losses.
Reclassification
Certain previously reported amounts have been reclassified to conform to the current year's presentation.
Recent Accounting Pronouncements
In March 2020, the FASBFinancial Accounting Standards Board ("FASB") issued ASU 2020-04, "Reference Rate Reform (Topic 848)-Facilitation of the Effects of Reference Rate Reform on Financial Reporting" ("ASU 2020-04") to provide optional expedients and exceptions for applying GAAP to certain contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments in this update apply only to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate ("LIBOR") or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships existing as of December 31, 2022, for which an entity has elected certain optional expedients provided that those elections are retained through the end of the hedging relationship. The amendments in this update are effective for all entities as of March 12, 2020 through December 31, 2022 and do not apply to contract modifications made after December 31, 2022.
In January 2021, the FASB issued ASU 2021-01, "Reference Rate Reform (Topic 848)" an update to address concerns around structural risk of interbank offered rates ("IBORs"), particularly, the risk of cessation of the LIBOR. The amendments in this update clarify that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. In December 2022, FASB issued ASU 2022-06, "Reference Rate Reform (Topic 848)" which deferred the sunset date of Topic 848 to December 31, 2024, to allow for a transition period after the sunset of LIBOR. The Company has adopted the amendments in these updates and established a LIBOR transition committee to guide the Company’s transition from LIBOR. The Company has completed much of the work to transition off the LIBOR index consistent with industry timelines. The working group has identified its products that utilize LIBOR and has implemented fallback language to facilitate the transition to alternative rates. The Company has also evaluated its infrastructure and identified fallback rates as well as started offering alternative indices and new products tied to these alternative indices. The Company does not anticipate the adoption of these standards to have a material impact to the consolidated financial statements.
In October 2021, the FASB issued ASU 2021-08, "Business Combinations (Topic 805), Accounting for Contract Assets and Contract Liabilities from Contracts with Customers" which requires that an acquirer recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606, Revenue from Contracts with Customers. At the acquisition date, an acquirer should account for the related revenue contracts in accordance with Topic 606 as if it had originated the contracts. The Company adopted ASU 2021-08 as of January 1, 2023 on a prospective basis. The adoption did not have a material impact on the Company's consolidated financial statements.
In March 2022, the FASB issued ASU 2022-02, "Financial Instruments - Credit Losses (Topic 326), Troubled Debt Restructurings and Vintage Disclosures" which addresses concerns regarding the complex accounting for loans modified as troubled debt restructurings (“TDRs”) and also the disclosure of gross writeoff information included in required vintage disclosures. The Company adopted ASU 2022-02 as of January 1, 2023. The enhanced disclosure requirements provided for by ASU 2022-02 were adopted on a prospective basis. Reporting periods prior to the adoption of ASU 2022-02 are presented in accordance with the applicable GAAP. The adoption did not have a material impact on the Company’s consolidated financial statements. Additional details can be found in Note 5, "Allowance for Credit Losses".

(2) Acquisitions
PCSB Financial Corporation

Pursuant to the merger agreement, each share of PCSB common stock outstanding at the effective time of the merger was converted into the right to receive, at the holder’s election, either $22.00 in cash consideration or 1.3284 shares of Company common stock for each share of PCSB common stock, subject to allocation procedures to ensure that 60% of the outstanding shares of PCSB common stock was converted to Company common stock. PCSB’s bank subsidiary, PCSB Bank, operates as a separate subsidiary of the Company and has 1514 banking offices throughout the Lower Hudson Valley of New York State.
The transaction was accounted for as a business combination. Accordingly, the purchase price was allocated to the assets acquired and liabilities assumed based on their fair values as of the merger effective date. The determination of fair value required management to make estimates about discount rates, future expected cash flows, market conditions, and other future events that are highly subjective in nature and are subject to change. Fair value estimates of the assets acquired and liabilities assumed may be adjusted for a period up to one year (the measurement period) from the closing date of the merger if new information is obtained about facts and circumstances that existed as of the merger effective date that, if known, would have affected the measurement of the amounts recognized as of that date.
During the three and six months ended JuneSeptember 30, 2023, the Company did not incur any merger-related expenses. During the nine months ended September 30, 2023, the Company incurred merger-related expenses totaling $1.0 million and $7.4 million, respectively.million.

Notes to Unaudited Consolidated Financial Statements (Continued)
Fair values of the major categories of assets acquired and liabilities assumed were determined as follows:
Cash and Cash Equivalents
The fair values of cash and cash equivalents approximate the respective carrying amounts because the instruments are payable on demand or have short-term maturities.
Investments
The fair values for investment securities available-for-sale were based on quoted market prices, where available. If quoted market prices were not available, fair value estimates are generally based on observable inputs, including quoted market prices for similar instruments. Investment securities held-to-maturity were reclassified to investment securities available-for-sale based on the Company's intent at closing.
During the sixnine months ended JuneSeptember 30, 2023, the Company restructured the investment portfolio acquired from PCSB. The Company sold approximately 75% of the portfolio which equates to $228.3 million of book value of predominantly longer dated Agency MBS,mortgage-backed securities ("MBS"), Agency CMOs, Corporatecollateralized mortgage obligations ("CMOs"), corporate and Municipalmunicipal securities. The weighted average duration of these securities was 6.1 years with an average risk weighting of assets of 33%. The Company recognized a $1.7 million gain from selling these securities.
Proceeds from the sale and additional cash on hand was used to purchase $295.6$318.5 million of short duration securities, the majority of which are US Treasuries, Agency MBS, and a small position of short term Municipal Bond Anticipation Notes. Additional details can be found in Note 3, "Investment Securities".
The weighted average duration of these securities was 2.1 years with an average risk weighting of assets of 4%.
Loans
The fair value of the loan portfolio was calculated on an individual loan basis using discounted cash flow analysis, with results presented and assumptions applied on a summary basis. This analysis took into consideration the contractual terms of the loans and assumptions related to the cost of debt, cost of equity, servicing cost and other liquidity/risk premium considerations to estimate the projected cash flows. The loss rates for the loans were estimated using Probability of Default (cumulative) and Loss Given Default assumptions. The assumptions used in determining the fair value of the loan portfolio were considered reasonable from a market-participant viewpoint.
The Company recorded a $49.8 million discount from the results of the loan accounting valuation.
Deposits - Core Deposits Intangible ("CDI")
Accounts included in the CDI include demand deposits, NOW accounts, money market accounts and savings accounts. The fair value of the CDI was derived from using a financial institution-specific income approach. Factors examined in the valuation of the CDI include customer attrition, deposit interest rates, service charge income, overhead expense, and costs of alternative funding.
The Company recorded a $30.3 million CDI from the results of the deposit valuation. The CDI is being amortized at an accelerated rate over 7 years using the sum-of-the-years method.
Certificates of Deposits
The certificates of deposits were recorded at fair value. The determination of the fair value was calculated using discounted cash flow analysis, which involved present valuing the contractual payments over the remaining life of the certificate of deposit at market based-rates.
The Company recorded a $3.2 million discount from the results of the certificate of deposit valuation.
Borrowings
The fair value of the FHLB advances were ascertained by using discounted cash flow analysis of the contractual payments over the remaining life of the advances at market-based interest rates. The FHLB advances were disaggregated on an individual advance basis and management used FHLB of New York rates as of December 30, 2022 as the market rate in the present value calculation.

The Company recorded a $0.3 million discount on the assumed FHLB advances.
PCD Loans and Leases
Purchased loans and leases that have experienced more-than-insignificant deterioration in credit quality since origination are considered purchase credit deteriorated ("PCD"). For PCD loans and leases, the initial estimate of expected credit losses was established through an adjustment to the unpaid principal balance and non-credit discount at acquisition.

As of JuneSeptember 30, 2023 and December 31, 2022, respectively, $575.0$608.8 million and $387.9 million of investment securities were pledged as collateral for repurchase agreements; municipal deposits; treasury, tax and loan deposits; swap agreements; FRB borrowings; and FHLB of Boston and FHLB of New York borrowings. The Banks had no outstanding FRB borrowings as of JuneSeptember 30, 2023 and December 31, 2022.
Allowance for Credit Losses-Available-for-Sale Securities
For available-for-sale securities in an unrealized loss position, management first assesses whether (i) the Company intends to sell the security, or (ii) it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis. If either criterion is met, any previously recognized allowances are charged-off and the security's amortized cost is written down to fair value through income. If neither criterion is met, the security is evaluated to determine whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency and any adverse conditions specifically related to the security, among other factors.
If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security is compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, an allowance for credit loss is recorded, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through the Allowance for Credit Losses ("ACL") is recognized in other comprehensive income. Adjustments to the allowance are reported as a component of credit loss expense. Available-for-sale securities are charged-off against the allowance or, in the absence of any allowance, written down through income when deemed uncollectible or when either of the aforementioned criteria regarding intent or requirement to sell is met. The Company has made the accounting policy election to exclude accrued interest receivable on available-for-sale securities from the estimate of credit losses. Accrued interest receivables associated with debt securities available-for-sale totaled $4.0$3.9 million as of JuneSeptember 30, 2023 compared to $2.6 million to as of December 31, 2022.
A debt security is placed on nonaccrual status at the time any principal or interest payments become more than 90 days delinquent or if full collection of interest or principal becomes uncertain. Accrued interest for a debt security placed on nonaccrual is reversed against interest income. There were no debt securities on nonaccrual status and therefore there was no accrued interest related to debt securities reversed against interest income for the sixnine months ended JuneSeptember 30, 2023 and 2022.

The Company performs regular analyses of the investment securities available-for-sale portfolio to determine whether a decline in fair value indicates that an investment security is impaired. In making these impairment determinations, management considers, among other factors, projected future cash flows; credit subordination and the creditworthiness; capital adequacy and near-term prospects of the issuers.
Management also considers the Company's capital adequacy, interest-rate risk, liquidity and business plans in assessing whether it is more likely than not that the Company will sell or be required to sell the investment securities before recovery. If the Company determines that a security investment is impaired and that it is more likely than not that the Company will not sell or be required to sell the investment security before recovery of its amortized cost, the credit portion of the impairment loss is recognized in the Company's consolidated statement of income and the noncredit portion is recognized in accumulated other comprehensive income. The credit portion of the impairment represents the difference between the amortized cost and the present value of the expected future cash flows of the investment security. If the Company determines that a security is impaired and it is more likely than not that it will sell or be required to sell the investment security before recovery of its amortized cost, the entire difference between the amortized cost and the fair value of the security will be recognized in the Company's consolidated statement of income.
Investment Securities Available-For-Sale Impairment Analysis
The following discussion summarizes, by investment security type, the basis for evaluating if the applicable investment securities within the Company’s available-for-sale portfolio were impaired as of JuneSeptember 30, 2023. The Company has determined it is more likely than not that the Company will not sell or be required to sell the investment securities before recovery of its amortized cost. The Company's ability and intent to hold these investment securities until recovery is supported by the Company's strong capital and liquidity positions as well as its historically low portfolio turnover. As such, management has determined that the investment securities are not impaired as of JuneSeptember 30, 2023. If market conditions for investment securities worsen or the creditworthiness of the underlying issuers deteriorates, it is possible that the Company may recognize additional impairment in future periods.
U.S. Government-Sponsored Enterprises
The Company invests in securities issued by U.S. Government-sponsored enterprises ("GSEs"), including GSE debentures, mortgage-backed securities ("MBSs"), and collateralized mortgage obligations ("CMOs"). GSE securities include obligations issued by the Federal National Mortgage Association ("FNMA"), the Federal Home Loan Mortgage Corporation ("FHLMC"), the Government National Mortgage Association ("GNMA"), the FHLB and the Federal Farm Credit Bank. As of JuneSeptember 30, 2023, the Company held GNMA MBSs and CMOs, and Small Business Administration ("SBA") commercial loan asset-backed securities in its available-for-sale portfolio with an estimated fair value of $33.8$31.1 million, all of which were backed explicitly by the full faith and credit of the U.S. Government, compared to $2.7 million as of December 31, 2022.
As of September 30, 2023, the Company owned 40 GSE debentures with a total fair value of $168.9 million, and a net unrealized loss of $26.6 million. The acquisition of PCSB accounted for $39.9 million of the total fair value at September 30,

Actual maturities of debt securities will differ from those presented above since certain obligations amortize and may also provide the issuer the right to call or prepay the obligation prior to scheduled maturity without penalty. MBSs and CMOs are included above based on their final stated maturities; the actual maturities, however, may occur earlier due to anticipated prepayments and stated amortization of cash flows.
As of JuneSeptember 30, 2023, issuers of debt securities with an estimated fair value of $95.0$90.8 million had the right to call or prepay the obligations. Of the $95.0$90.8 million, approximately $5.4$9.3 million matures in less then 1 year, $35.2$28.8 million matures in 1-5 years, $46.8$45.6 million matures in 6-10 years, and $7.6$7.1 million matures after ten years. As of December 31, 2022, issuers of debt securities with an estimated fair value of approximately $53.1 million had the right to call or prepay the obligations. Of the $53.1 million, approximately $2.5 million matures in less then 1 year, $6.3 million matures in 1-5 years, $37.4 million matures in 6-10 years, and $6.9 million matures after ten years.
Security Sales
The proceeds from the sale of investment securities available-for-sale were $230.0 million during the sixnine months ended JuneSeptember 30, 2023, compared to the sixnine months ended JuneSeptember 30, 2022 where the Company did not sell any investment securities available-for-sale. Securities sales executed during the sixnine months ended were related to the acquisition of PCSB and the restructuring of the acquired investment portfolio.

Allowance for Loan and Lease Losses Methodology
Management has established a methodology to determine the adequacy of the allowance for credit losses that assesses the risks and losses expected on the loan and lease portfolio and unfunded commitments. Additions to the allowance for credit losses are made by charges to the provision for credit losses. Losses on loans and leases are charged off against the allowance when all or a portion of a loan or lease is considered uncollectible. Subsequent recoveries on loans previously charged off, if any, are credited to the allowance when realized.
To calculate the allowance for loans collectively evaluated, management uses models developed by a third party. Commercial real estate ("CRE"), commercial and industrial ("C&I"), and retail lifetime loss rate models calculate the expected losses over the life of the loan based on exposure at default loan attributes and reasonable, supportable economic forecasts. The exposure at default considers the current unpaid balance, prepayment assumptions and expected utilization assumptions. The expected loss estimates for two small commercial portfolios are based on historical loss rates.
Key assumptions used in the models include portfolio segmentation, prepayments, and the expected utilization of unfunded commitments, among others. The portfolios are segmented by loan level attributes such as loan type, loan size, date of origination, and delinquency status to create homogenous loan pools. Pool level metrics are calculated and loss rates are subsequently applied to the pools as the loans have like characteristics. Prepayment assumptions are embedded within the models and are based on the same data used for model development and incorporate adjustments for reasonable and supportable forecasts. Model development data and developmental time periods vary by model, but all use at least ten years of historical data and capture at least one recessionary period. Expected utilization is based on current utilization and a loan equivalency ("LEQ") factor. LEQ varies by current utilization and provides a reasonable estimate of expected draws and borrower behavior.

BROOKLINE BANCORP, INC. AND SUBSIDIARIES
Notes to Unaudited Consolidated Financial Statements (Continued)
Assumptions and model inputs are reviewed in accordance with model monitoring practices and as information becomes available.
The ACL estimate incorporates reasonable and supportable forecasts of various macro-economic variables over the remaining life of loans and leases. The development of the reasonable and supportable forecast assume each macro-economic variable will revert to long-term expectations, with reversion characteristics unique to specific economic indicators and forecasts. Reversion towards long-term expectations generally begins two to three years from the forecast start date and largely completes within the first five years. Because the reasonable and supportable economic forecasts used in the models are mean reverting, the models are therefore considered to be implicitly mean reverting.

Management elected to use multiple economic forecasts in determining the reserve to account for economic uncertainty. The forecasts include various projections of gross domestic product ("GDP"), interest rates, property price indices, and employment measures. Scenario weighting and model parameters are reviewed for each calculation and updated to reflect facts and circumstances as of the financial statement date. The forecasts utilized at JuneSeptember 30, 2023 reflect the immediate and longer-term effects of a rising interest rate environment and inflationary conditions.

As of JuneSeptember 30, 2023, management applied qualitative adjustments to the CRE lifetime loss rate, C&I lifetime loss rate, and Retail lifetime loss rate models. These adjustments addressed model limitations, were based on historical loss patterns, and targeted specific risks within the certain portfolios. A general qualitative adjustment was applied to all models to account for general economic uncertainty by placing a greater probability on negative economic forecasts. Additional qualitative adjustments were applied to the commercial, multifamily, and commercial real estate (includes owner occupied, non-owner occupied, and construction) portfolios based on the Company’s historical loss experience and the loss experience of the Company’s peer group. High risk segments of the Eastern Funding portfolios also received additional qualitative adjustments based on recent loss history and expected liquidation values. These qualitative adjustments resulted in additions to reserves for all portfolios, as compared to the model output.
Specific reserves are established for loans individually evaluated for impairment when amortized cost basis is greater than the discounted present value of expected future cash flows or, in the case of collateral-dependent loans, when there is an excess of a loan's amortized cost basis over the fair value of its underlying collateral. When loans and leases do not share risk characteristics with other financial assets they are evaluated individually. Individually evaluated loans are reviewed quarterly with adjustments made to the calculated reserve as necessary.
The general allowance for loan and lease losses was $111.0$108.6 million as of JuneSeptember 30, 2023, compared to $95.4 million as of December 31, 2022. The increase in the general allowance was primarily driven by the acquisition of PCSB Bank during the year, which contributed $14.8 million of the $15.6$13.2 million increase, and secondarilywas offset by loan growth duringan overall decrease in the year.general allowance of all entities, excluding PCSB Bank.

The specific allowance for loan and lease losses was $14.8$10.5 million as of JuneSeptember 30, 2023, compared to $3.1 million as of December 31, 2022. The specific allowance increased by $11.7$7.4 million during the sixnine months ended JuneSeptember 30, 2023 primarily due to specific reserves on two C&I accounts totaling $6 million, as well as specific reserve increases totaling $2.9$4.2 million for commercial loans and $3.2 million for commercial real estate loans and $2.2 million in equipment financing loans.
As of JuneSeptember 30, 2023, management believes that the methodology for calculating the allowance is sound and that the allowance provides a reasonable basis for determining and reporting on expected losses over the lifetime of the Company’s loan portfolios.
Credit Quality Assessment
At the time of loan origination, a rating is assigned based on the capacity to pay and general financial strength of the borrower, the value of assets pledged as collateral, and the evaluation of third party support such as a guarantor. The Company continually monitors the credit quality of the loan portfolio using all available information. The officer responsible for handling each loan is required to initiate changes to risk ratings when changes in facts and circumstances occur that warrant an upgrade or downgrade in a loan rating. Based on this information, loans demonstrating certain payment issues or other weaknesses may be categorized as delinquent, adversely risk-rated, nonperforming and/or put on nonaccrual status. Additionally, in the course of resolving such loans, the Company may choose to restructure the contractual terms of certain loans to match the borrower's ability to repay the loan based on their current financial condition. If a restructured loan meets certain criteria, it may be categorized as a modified loan.

Notes to Unaudited Consolidated Financial Statements (Continued)
The Company reviews numerous credit quality indicators when assessing the risk in its loan portfolio. For all loans, the Company utilizes an eight-grade loan rating system, which assigns a risk rating to each borrower based on a number of quantitative and qualitative factors associated with a loan transaction. Factors considered include industry and market conditions; position within the industry; earnings trends; operating cash flow; asset/liability values; debt capacity; guarantor strength; management and controls; financial reporting; collateral; and other considerations. In addition, the Company's independent loan review group evaluates the credit quality and related risk ratings in all loan portfolios. The results of these reviews are reported to the Risk Committee of the Board of Directors on a periodic basis and annually to the Board of Directors. For the consumer loans, the Company heavily relies on payment status for calibrating credit risk.
The ratings categories used for assessing credit risk in the commercial real estate, multi-family mortgage, construction, commercial, equipment financing, condominium association and other consumer loan and lease classes are defined as follows:
1 -4 Rating—Pass
Loan rating grades "1" through "4" are classified as "Pass," which indicates borrowers are performing in accordance with the terms of the loan and are less likely to result in loss due to the capacity of the borrower to pay and the adequacy of the value of assets pledged as collateral.
5 Rating—Other Assets Especially Mentioned ("OAEM")
Borrowers exhibit potential credit weaknesses or downward trends deserving management's attention. If not checked or corrected, these trends will weaken the Company's asset and position. While potentially weak, currently these borrowers are marginally acceptable; no loss of principal or interest is envisioned.
6 Rating—Substandard
Borrowers exhibit well defined weaknesses that jeopardize the orderly liquidation of debt. Substandard loans may be inadequately protected by the current net worth and paying capacity of the obligors or by the collateral pledged, if any. Normal repayment from the borrower is in jeopardy. Although no loss of principal is envisioned, there is a distinct possibility that a partial loss of interest and/or principal will occur if the deficiencies are not corrected. Collateral coverage may be inadequate to cover the principal obligation.
7 Rating—Doubtful
Borrowers exhibit well-defined weaknesses that jeopardize the orderly liquidation of debt with the added provision that the weaknesses make collection of the debt in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Serious problems exist to the point where partial loss of principal is likely.
8 Rating—Definite Loss
Borrowers deemed incapable of repayment. Loans to such borrowers are considered uncollectible and of such little value that continuation as active assets of the Company is not warranted.
Assets rated as "OAEM," "substandard" or "doubtful" based on criteria established under banking regulations are collectively referred to as "criticized" assets.

Impaired Loans and Leases
A loan is considered to be impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due (both interest and principal) according to the contractual terms of the loan agreement. The loans and leases risk-rated "substandard" or worse are considered impaired. The Company has also defined the population of impaired loans to include nonaccrual loans and modified loans. Impaired loans and leases which do not share similar risk characteristics with other loans are individually evaluated for credit losses. Specific reserves are established for loans and leases with deterioration in the present value of expected future cash flows or, in the case of collateral-dependent loans and leases, any increase in the loan or lease amortized cost basis over the fair value of the underlying collateral discounted for estimated selling costs. In contrast, the loans and leases which share similar risk characteristics and are not included in the individually evaluated population are collectively evaluated for credit losses.

Loan Modifications
In January 2023, the Company adopted ASU 2022-02, “Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures” (“ASU 2022-02”), which eliminated the accounting guidance for troubled debt restructurings (“TDRs”)TDRs while enhancing disclosure requirements for certain loan refinancing and restructurings by creditors when a borrower is experiencing financial difficulty. This guidance was applied on a prospective basis. Upon adoption of this guidance, the Company estimates the reserve for modifications to borrowers experiencing financial difficulty in a manner similar to the process for non-modified loans.
The following tables present the amortized cost basis of loan modifications made to borrowers experiencing financial difficulty during the periods indicated.The loans presented in the following tables relate to twothree customer relationships.

(8) Derivatives and Hedging Activities
The Company executes loan level derivative products such as interest rate swap agreements with commercial banking customers to aid them in managing their interest rate risk. The interest rate swap contracts allow the commercial banking customers to convert floating rate loan payments to fixed rate loan payments. The Company concurrently enters into offsetting swaps with a third party financial institution, effectively minimizing its net risk exposure resulting from such transactions. The third party financial institution exchanges the customer's fixed rate loan payments for floating rate loan payments. As the interest rate swap agreements associated with this program do not meet hedge accounting requirements, changes in the fair value are recognized directly in earnings. Based on the Company's intended use for the loan level derivatives at inception, the Company designates the derivative as either an economic hedge of an asset or liability, or a hedging instrument subject to the hedge accounting provisions of FASB ASC Topic 815, "Derivatives and Hedging".
The Company believes using interest rate derivatives adds stability to interest income and expense and allows the Company to manage its exposure to interest rate movements. The Company enters into interest rate swaps as part of its interest rate risk management strategy. These interest rate swaps are designated as cash flow hedges and involve the receipt of variable rate amounts from a counterparty in exchange for the Company making fixed payments. The Company enters into interest rate swaps as hedging instruments against the interest rate risk associated with the Company's FHLB borrowings and loan portfolio. For derivative instruments that are designated and qualify as cash flow hedging instruments, the effective portion of the gains or losses is reported as a component of other comprehensive income ("OCI"), and is reclassified into earnings in the period that the hedged forecasted transaction affects earnings.
The following table reflects the Company's derivative positions as of the date indicated below for interest rate derivatives which qualify as cash flow hedges for accounts purposes.

The Company utilizes risk participation agreements with other banks participating in commercial loan arrangements. Participating banks guarantee the performance on borrower-related interest rate swap contracts. Risk participation agreements are derivative financial instruments and are recorded at fair value. These derivatives are not designated as hedges and therefore, changes in fair value are recorded directly through earnings in other non-interest income at each reporting period. Under a risk participation-out agreement, a derivative asset, the Company participates out a portion of the credit risk associated with the interest rate swap position executed with the commercial borrower, for a fee paid to the participating bank.
The Company offers foreign exchange contracts to commercial borrowers to accommodate their business needs. These foreign exchange contracts do not qualify as hedges for accounting purposes. To mitigate the market and liquidity risk associated with these foreign exchange contracts, the Company enters into similar offsetting positions.
Asset derivatives and liability derivatives are included in other assets and accrued expenses and other liabilities on the unaudited consolidated balance sheets.

The Brookline Bancorp, Inc. 2011 Restricted Stock Plan (the "2011 Plan") expired in July 2021, and the Company has not issued shares from the 2011 Plan since the adoption of the 2014 Plan. The 2021 Plan and the 2014 Plan are together referred to as the "Plans."

Of the awarded shares under the Plans, generally 50% vest ratably over three years with one-third of such shares vesting at each of the first, second and third anniversary dates of the awards. These are referred to as "time-based shares". The remaining 50% of each award will vest three years after the award date based on the level of the Company's achievement of identified performance targets in comparison to the level of achievement of such identified performance targets by a defined peer group. These are referred to as "performance-based shares". If a participant leaves the Company prior to the third anniversary date of an award, any unvested shares are usually forfeited. Dividends declared with respect to shares awarded will be held by the Company and paid to the participant only when the shares vest.

Under the Plans, shares of the Company's common stock are reserved for issuance as restricted stock awards to officers, employees, and non-employee directors of the Company. Shares issued upon vesting may be either authorized but unissued shares or reacquired shares held by the Company as treasury shares. Any shares not issued because vesting requirements are not met will be retired back to treasury and be made available again for issuance under the Plans.

During the three and sixnine months ended JuneSeptember 30, 2023 and JuneSeptember 30, 2022, no449,265 and 310,349 shares were issued, respectively, upon satisfaction of required conditions of the Plans.

Total expense for the Plans was $0.9$1.0 million and $0.8$0.9 million for the three months ended JuneSeptember 30, 2023 and 2022, respectively. Total expense for the Plan was $1.8$2.8 million and $1.6$2.4 million for the sixnine months ended JuneSeptember 30, 2023 and 2022, respectively.

Investment Securities Available-for-Sale
The fair value of investment securities is based principally on market prices and dealer quotes received from third-party and nationally-recognized pricing services for identical investment securities such as U.S. Treasury and agency securities. These prices are validated by comparing the primary pricing source with an alternative pricing source when available. When quoted market prices for identical securities are unavailable, the Company uses market prices provided by independent pricing services based on recent trading activity and other observable information, including but not limited to market interest-rate curves, referenced credit spreads and estimated prepayment speeds, where applicable. These investments include GSE debentures, GSE mortgage-related securities, SBA commercial loan asset backed securities, corporate debt obligations, municipal obligations and trust preferred securities, all of which are included in Level 2. As of JuneSeptember 30, 2023, $19.6$22.6 million of investment securities available-for-sale are included in Level 3 within the investment portfolio. The composition of these assets are primarily composed of subordinated debt of local banks and private placement municipal securities. Of these securities, approximately $14.6$15.3 million are private placement municipal Bond Anticipation Notes. As of December 31, 2022, none of the investment securities were valued using pricing models included in Level 3.
Additionally, management reviews changes in fair value from period to period and performs testing to ensure that prices received from the third parties are consistent with management's expectation of the market. Changes in the prices obtained from the pricing service are analyzed from month to month, taking into consideration changes in market conditions including changes in mortgage spreads, changes in U.S. Treasury security yields and changes in generic pricing of 15-year and 30-year securities. Additional analysis may include a review of prices provided by other independent parties, a yield analysis, a review of average life changes using Bloomberg analytics and a review of historical pricing for a particular security.
Derivatives and Hedging Instruments
The fair value of interest rate derivatives designated as hedging instruments, loan level derivatives, risk participation agreements (RPA in/out), and foreign exchange contracts represent a Level 2 valuation and are based on settlement values adjusted for credit risks associated with the counterparties and the Company and observable market interest rate curves and foreign exchange rates where applicable. Credit risk adjustments consider factors such as the likelihood of default by the Company and its counterparties, its net exposures and remaining contractual life. To date, the Company has not realized any

Collateral-Dependent Impaired Loans and Leases
For nonperforming loans and leases where the credit quality of the borrower has deteriorated significantly, fair values of the underlying collateral were estimated using purchase and sales agreements (Level 2), or comparable sales or recent appraisals (Level 3), adjusted for selling costs and other expenses.
Other Real Estate Owned ("OREO")
The Company records OREO at the lower of cost or fair value. In estimating fair value, the Company utilizes purchase and sales agreements (Level 2) or comparable sales, recent appraisals or cash flows discounted at an interest rate commensurate with the risk associated with these cash flows (Level 3), adjusted for selling costs and other expenses. As of JuneSeptember 30, 2023 and December 31, 2022, the Company did not record any OREO.
Repossessed Assets
Repossessed assets are carried at estimated fair value less costs to sell based on auction pricing (Level 2).

Appraisal of collateral (1)

(1) Fair value is generally determined through independent appraisals of the underlying collateral. The Company may also use another available source of collateral assessment to determine a reasonable estimate of the fair value of the collateral. Appraisals may be adjusted by management for qualitative factors such as economic factors and estimated liquidation expenses. The range of the unobservable inputs used may vary but is generally 0% - 10% on the discount for costs to sell and 0% - 15% on appraisal adjustments.

Loans and Leases
The fair values of performing loans and leases was estimated by segregating the portfolio into its primary loan and lease categories—commercial real estate mortgage, multi-family mortgage, construction, commercial, equipment financing, condominium association, residential mortgage, home equity and other consumer. These categories were further disaggregated based upon significant financial characteristics such as type of interest rate (fixed / variable) and payment status (current / past-due). Using the exit price valuation method, the Company discounts the contractual cash flows for each loan category using interest rates currently being offered for loans with similar terms to borrowers of similar quality and incorporates estimates of future loan prepayments.
Deposits
The fair values of deposit liabilities with no stated maturity (demand, NOW, savings and money market savings accounts) are equal to the carrying amounts payable on demand. The fair value of certificates of deposit represents contractual cash flows discounted using interest rates currently offered on deposits with similar characteristics and remaining maturities. The fair value estimates for deposits do not include the benefit that results from the low-cost funding provided by the Company's core deposit relationships (deposit-based intangibles).

Borrowed Funds
The fair value of federal funds purchased is equal to the amount borrowed. The fair value of FHLB advances and repurchase agreements represents contractual repayments discounted using interest rates currently available for borrowings with similar characteristics and remaining maturities. The fair values reported for retail repurchase agreements are based on the discounted value of contractual cash flows. The discount rates used are representative of approximate rates currently offered on borrowings with similar characteristics and maturities. The fair values reported for subordinated deferrable interest debentures are based on the discounted value of contractual cash flows. The discount rates used are representative of approximate rates currently offered on instruments with similar terms and maturities.
(12) Commitments and Contingencies
Off-Balance Sheet Financial Instruments
The Company is party to off-balance sheet financial instruments in the normal course of business to meet the financing needs of its customers and to reduce its own exposure to fluctuations in interest rates. These financial instruments include loan commitments, standby and commercial letters of credit, and loan level derivatives. According to GAAP, these financial instruments are not recorded in the financial statements until they are funded or related fees are incurred or received.
The contract amounts reflect the extent of the involvement the Company has in particular classes of these instruments. Such commitments involve, to varying degrees, elements of credit risk and interest-rate risk in excess of the amount recognized in the consolidated balance sheets. The Company's exposure to credit loss in the event of non-performance by the counterparty is represented by the fair value of the instruments. The Company uses the same policies in making commitments and conditional obligations as it does for on-balance sheet instruments.

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require the payment of a fee by the customer. Since some of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer's creditworthiness on a case-by-case basis. The amount of collateral obtained, if any, is based on management's credit evaluation of the borrower.
Standby and commercial letters of credit are conditional commitments issued by the Company to guarantee performance of a customer to a third party. These standby and commercial letters of credit are primarily issued to support the financing needs of the Company's commercial customers. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loans to customers.
From time to time, the Company enters into loan level derivatives, risk participation agreements or foreign exchange contracts with commercial customers and third-party financial institutions. These derivatives allow the Company to offer long-term fixed-rate commercial loans while mitigating the interest-rate or foreign exchange risk of holding those loans. In a loan level derivative transaction, the Company lends to a commercial customer on a floating-rate basis and then enters into a loan level derivative with that customer. Concurrently, the Company enters into offsetting swaps with a third-party financial institution, effectively minimizing its net interest-rate risk exposure resulting from such transactions. The fair value of these derivatives are presented in Note 8.

Lease Commitments
The Company leases certain office space under various noncancellable operating leases as well as certain other assets. These leases have original terms ranging from 1 year to over 25 years. Certain leases contain renewal options and escalation clauses which can increase rental expenses based principally on the consumer price index and fair market rental value provisions. All of the Company's current outstanding leases are classified as operating leases.
The Company considered the following criteria when determining whether a contract contains a lease, the existence of an identifiable asset and the right to obtain substantially all of the economic benefits from use of the asset through the period. The Company uses the FHLB classic advance rates available as of the lease's start dates as the discount rate to determine the net present value of the remaining lease payments.
Total lease commitments increased from $19.5 million as of December 31, 2022 to $33.0$32.8 million as of JuneSeptember 30, 2023. The increase is due to the addition of 12 leases for PCSB Bank branch locations.

(13) Revenue from Contracts with Customers
Overview
Revenue from contracts with customers in the scope of ASC 606 ("Topic 606") is measured based on the consideration specified in the contract with a customer and excludes amounts collected on behalf of third parties. The Company recognizes revenue from contracts with customers when it satisfies its performance obligations.
The Company’s performance obligations are generally satisfied as services are rendered and can either be satisfied at a point in time or over time. Unsatisfied performance obligations at the report date are not material to our consolidated financial statements.
In certain cases, other parties are involved with providing services to our customers. If the Company is a principal in the transaction (providing services itself or through a third party on its behalf), revenues are reported based on the gross consideration received from the customer and any related expenses are reported in gross noninterest expense. If the Company is an agent in the transaction (referring to another party to provide services), the Company reports its net fee or commission retained as revenue.
A substantial portion of the Company’s revenue is specifically excluded from the scope of Topic 606. This exclusion is associated with financial instruments, including interest income on loans and investment securities, in addition to loan derivative income and gains on loan and investment sales. For the revenue that is in-scope of Topic 606, the following is a description of principal activities from which the Company generates its revenue from contracts with customers, separated by the timing of revenue recognition.

Revenue Recognized at a Point in Time
The Company recognizes revenue that is transactional in nature and such revenue is earned at a point in time. Revenue that is recognized at a point in time includes card interchange fees (fee income related to debit card transactions), ATM fees, wire transfer fees, overdraft charge fees, and stop-payment and returned check fees. Additionally, revenue is collected from loan fees, such as letters of credit, line renewal fees and application fees. Such revenue is derived from transactional information and is recognized as revenue immediately as the transactions occur or upon providing the service to complete the customer’s transaction.
Revenue Recognized Over Time
The Company recognizes revenue over a period of time, generally monthly, as services are performed and performance obligations are satisfied. Such revenue includes commissions on investments, insurance sales and service charges on deposit accounts. Fee revenue from service charges on deposit accounts represents the service charges assessed to customers who hold deposit accounts at the Banks.

Introduction
Brookline Bancorp, Inc., a Delaware corporation, operates as a multi-bank holding company for Brookline Bank and its subsidiaries; Bank Rhode Island and its subsidiaries ("BankRI"); PCSB Bank and its subsidiaries; Brookline Securities Corp; and Clarendon Private, LLC.
As a commercially-focused financial institution with 6364 full-service banking offices throughout greater Boston, the north shore of Massachusetts, Rhode Island and New York, the Company, through Brookline Bank, BankRI and PCSB Bank (collectively referred to as the "Banks"), offers a wide range of commercial, business and retail banking services, including a full complement of cash management products, foreign exchange services, on-line and mobile banking services, consumer and residential loans and investment advisory services, designed to meet the financial needs of small- to mid-sized businesses and individuals throughout central New England and the lower Hudson Valley in New York. The Banks and their subsidiaries lend primarily in all New England states and New York, with the exception of equipment financing, 29.6%29.2% of which is in the greater New York and New Jersey metropolitan area and 70.4%70.8% of which is in other areas in the United States of America as of JuneSeptember 30, 2023. Clarendon Private is a registered investment advisor with the SEC. Through Clarendon Private, the Company offers a wide range of wealth management services to individuals, families, endowments and foundations to help these clients meet their long-term financial goals.
The Company focuses its business efforts on profitably growing its commercial lending businesses, both organically and through acquisitions. The Company’s customer focus, multi-bank structure, and risk management are integral to its organic growth strategy and serve to differentiate the Company from its competitors. As full-service financial institutions, the Banks and their subsidiaries focus their efforts on developing and deepening long-term banking relationships with qualified customers through a full complement of products, excellent customer service, and strong risk management.

The Company manages the Banks under a uniform strategic objective, with one set of uniform policies consistently applied by one executive management team. Within this environment, the Company believes that the ability to make customer decisions locally enhances management's motivation, service levels and, as a consequence, the Company's financial results. As such, while most back-office functions are consolidated at the holding company level, branding and decision-making, including credit decisions and pricing, remain largely local in order to better meet the needs of bank customers and further motivate the Banks’ commercial, business and retail bankers. These credit decisions, at the local level, are executed through corporate policies overseen by the Company's credit department.
The competition for loans and leases and deposits remains strong. Loan and deposit growth are also influenced by the rate-setting actions of the Board of Governors of the Federal Reserve System (the "FRB"). Based on management's scenario analysis of deposit sensitivity to the current rate environment and customer's demand for non-depository investment alternatives, management expects that there will be further deposit mix migration and increased deposit sensitivity to interest rates, which will negatively impact net interest income and net interest margin.
Management expects pressure on the net interest margin to continue for a quarter or two after the Federal Reserve stops increasing rates, after which the net interest margin is expected to stabilize and then increase as loans continue to reprice into the higher rate environment faster than time deposits and other funding sources. Net interest income models, using a projected flat balance sheet with stable deposit balances and an average sensitivity of deposit rates of approximately 39% to market rates, forecast that a short-term increase in rates will positively affect the Company's net interest income, net interest spread, and net interest margin. It is management's expectation that even should interest rates rise, margin will continue to compress as rates on deposit products continue to "catch up" with the swift rise in short term rates over the last year.
As discussed above, changes in interest rates could also precipitate a change in the mix and volume of the Company's deposits and loans. The future operating results of the Company will depend on its ability to maintain or increase the current net interest income, manage credit risk, increase sources of non-interest income, while managing non-interest expenses.
The Company and the Banks are supervised, examined and regulated by the FRB. As a Massachusetts-chartered trust company, Brookline Bank is subject to supervision, examination and regulation by the Massachusetts Division of Banks. As a Rhode Island-chartered financial institution, BankRI is subject to examination, supervision and regulation by the Banking Division of the Rhode Island Department of Business Regulation. As a New York-chartered commercial bank, PCSB Bank is subject to regulation, supervision and examination by the New York State Department of Financial Services. The FDIC insures each of the Banks’ deposits up to $250,000 per depositor. As previously disclosed, on July 31, 2019, Brookline Bank converted to a Massachusetts-chartered trust company and ended its membership in the Depositors Insurance Fund (the “DIF”), a private industry-sponsored fund which insures deposit balances at Massachusetts-chartered savings banks and cooperative banks in excess of federal deposit insurance coverage. Brookline Bank’s growth in deposit size necessitated Brookline Bank’s withdrawal from the DIF and the concurrent charter conversion of Brookline Bank. Brookline Bank’s deposit accounts will continue to be insured by the deposit insurance fund of the FDIC up to applicable limits. Term deposits in excess of the FDIC insurance coverage as of July 31, 2019 will continue to be insured by the DIF until they reach maturity.
On January 1, 2023, the Company completed its previously announced acquisition (the “merger”) of PCSB. Pursuant to the merger agreement, each share of PCSB common stock outstanding at the effective time of the merger was converted into the right to receive, at the holder’s election, either $22.00 in cash consideration or 1.3284 shares of Company common stock for each share of PCSB common stock, subject to allocation procedures to ensure that 60% of the outstanding shares of PCSB common stock was converted to Company common stock. Subsequent to the acquisition, PCSB Bank operates as a separate subsidiary of the Company and has 14 banking offices throughout the Lower Hudson Valley of New York State.
The Company’s common stock is traded on the Nasdaq Global Select MarketSM under the symbol “BRKL.”

Critical Accounting Policies and Estimates
The SEC defines “critical accounting policies” as those involving significant judgments and difficult or complex assumptions by management, often as a result of the need to make estimates about matters that are inherently uncertain or variable, which have, or could have, a material impact on the carrying value of certain assets or net income. The preparation of financial statements in accordance with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, income and expenses, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates. As discussed in the Company’s 2022 Annual Report on Form 10-K, management has identified the determination of the allowance for credit losses and the review of goodwill for impairment as the Company’s most critical accounting policies.

Recent Accounting Developments
In March 2023, the FASB issued ASU 2023-02, "Investments – Equity Method and Joint Ventures (Topic 323), Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method" which allows entities to use the proportional amortization method to account for tax equity investments, under certain conditions. This ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years for public entities. Management has determined that ASU 2023-02 does apply to the Company and is currently determining the impact as of JuneSeptember 30, 2023.
Non-GAAP Financial Measures and Reconciliation to GAAP
In addition to evaluating the Company’s results of operations in accordance with GAAP, management periodically supplements this evaluation with an analysis of certain non-GAAP financial measures, such as operating earnings metrics, the return on average tangible assets, return on average tangible equity, the tangible equity ratio, tangible book value per share, and dividend payout ratio. Management believes that these non-GAAP financial measures provide information useful to investors in understanding the Company’s underlying operating performance and trends, and facilitates comparisons with the performance assessment of financial performance, including non-interest expense control, while the tangible equity ratio and tangible book value per share are used to analyze the relative strength of the Company’s capital position.

The Company's loan portfolio consists primarily of first mortgage loans secured by commercial, multi-family and residential real estate properties located in the Company's primary lending area, loans to business entities, including commercial lines of credit, loans to condominium associations and loans and leases used to finance equipment used by small businesses. The Company also provides financing for construction and development projects, home equity and other consumer loans.
The Company employs seasoned commercial lenders and retail bankers who rely on community and business contacts as well as referrals from customers, attorneys and other professionals to generate loans and deposits. Existing borrowers are also an important source of business since many of them have more than one loan outstanding with the Company. The Company's ability to originate loans depends on the strength of the economy, trends in interest rates, and levels of customer demand and market competition.
The Company's current policy is that a total credit exposure to one obligor relationship may not exceed $60.0 million unless approved by the Company's Credit Committee. As of JuneSeptember 30, 2023, there were four borrowers with loans and commitments over $60.0 million. The total of those loans and commitments was $271.0$260.0 million, or 2.35%2.3% of total loans and commitments, as of JuneSeptember 30, 2023. As of December 31, 2022, there were three borrowers with loans and commitments over

The Company has written underwriting policies to control the inherent risks in loan origination. The policies address approval limits, loan-to-value ratios, appraisal requirements, debt service coverage ratios, loan concentration limits and other matters relevant to loan underwriting.
Commercial Real Estate LoansAsset Quality
Nonperforming assets as of September 30, 2023 totaled $51.5 million, or 0.46% of total assets, compared to $15.3 million, or 0.17% of total assets, as of December 31, 2022. Net charge-offs for the three months ended September 30, 2023 were $11.0 million, or 0.47% of average loans and leases on an annualized basis, compared to net recoveries of $0.2 million, or (0.01)% of average loans and leases on an annualized basis, for the three months ended September 30, 2022.

Typically, commercial real estate loans are larger in size and involve a greater degree of risk than owner-occupied residential mortgage loans. Loan repayment is usually dependent on the successful operation and management of the properties and the value of the properties securing the loans. Economic conditions can greatly affect cash flows and property values.
A number of factors are considered in originating commercial real estate and multi-family mortgage loans. The qualifications and financial condition of the borrower (including credit history), as well as the potential income generation and the value and condition of the underlying property, are evaluated. When evaluating the qualifications of the borrower, the Company considers the financial resources of the borrower, the borrower's experience in owning or managing similar property and the borrower's payment history with the Company and other financial institutions. Factors considered in evaluating the underlying property include the net operating income of the mortgaged premises before debt service and depreciation, the debt service coverage ratio (the ratio of cash flow before debt service to debt service), the use of conservative capitalization rates, and the ratio of the allowance for loan amountand lease losses to the appraised value. Generally, personal guarantees are obtained from commercial real estate loan borrowers.
Commercial real estatenonaccrual loans and multi-family mortgage loans are typically originated for terms of five to fifteen years with amortization periods of 20 to 30 years. Many of the loans are priced at inception on a fixed-rate basis generally for periods ranging from two to five years with repricing periods for longer-term loans. When possible, prepayment penalties are included in loan covenants on these loans. For commercial customers who are interested in loans with terms longer than five years, the Company offers loan level derivatives to accommodate customer need.
The Company's urban and suburban market area is characterized by a large number of apartment buildings, condominiums and office buildings. As a result, commercial real estate and multi-family mortgage lending has been a significant part of the Company's activities for many years. These types of loans typically generate higher yields, but also involve greater credit risk. Many of the Company's borrowers have more than one multi-family or commercial real estate loan outstanding with the Company.
The Company's commercial real estate portfolio is composed primarily of loans secured by apartment buildings ($1.3 billion), office buildings ($844.0 million), retail stores ($954.2 million), industrial properties ($780.4 million), mixed-use properties ($509.7 million), lodging services ($196.0 million), and food services ($79.4 million)leases was 232.39% as of JuneSeptember 30, 2023. At that date, approximately 78.3%2023, compared to 661.22% as of the commercial real estate loans outstanding were secured by properties located in New England.
Construction and development financing is generally considered to involve a higher degree of risk than long-term financing on improved, occupied real estate and thus has lower concentration limits than do other commercial credit classes. Risk of loss on a construction loan is largely dependent upon the accuracy of the initial estimate of construction costs, the estimated time to sell or rent the completed property at an adequate price or rate of occupancy, and market conditions. If the estimates and projections prove to be inaccurate, the Company may be confronted with a project which, upon completion, has a value that is insufficient to assure full loan repayment.
Criteria applied in underwriting construction loans for which the primary source of repayment is the sale of the property are different from the criteria applied in underwriting construction loans for which the primary source of repayment is the stabilized cash flow from the completed project. For those loans where the primary source of repayment is from resale of the property, in addition to the normal credit analysis performed for other loans, the Company also analyzes project costs, the attractiveness of the property in relation to the market in which it is located and demand within the market area. For those construction loans where the source of repayment is the stabilized cash flow from the completed project, the Company analyzes not only project costs but also how long it might take to achieve satisfactory occupancy and the reasonableness of projected rental rates in relation to market rental rates.December 31, 2022.

Critical Accounting Policies and Estimates
The Company also participatesSEC defines “critical accounting policies” as those involving significant judgments and difficult or complex assumptions by management, often as a result of the need to make estimates about matters that are inherently uncertain or variable, which have, or could have, a material impact on the carrying value of certain assets or net income. The preparation of financial statements in accordance with U.S. Government programs suchgenerally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, income and expenses, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates. As discussed in the Company’s 2022 Annual Report on Form 10-K, management has identified the determination of the allowance for credit losses and the review of goodwill for impairment as the SBA 7A program and as an SBA preferred lender. Included in the commercial loans balances are the PPP loans totaling $0.3 million as of June 30, 2023.
The Company’s equipment financing divisions focus on market niches in which its lenders have deep experience and industry contacts, and on making loans to customers with business experience. An important part of the Company’s equipment financing loan origination volume comes from equipment manufacturers and existing customers as they expand their operations. The equipment financing portfolio is composed primarily of loans to finance laundry, tow trucks, fitness, dry cleaning and convenience store equipment. Approximately 17.6% of the commercial loans outstanding in the equipment financing divisions were made to borrowers located primarily in the greater New York and New Jersey metropolitan area. Typically, the loans are priced at a fixed rate of interest and require monthly payments over their 3- to 7-year life. The yields earned on equipment financing loans are higher than those earned on the commercial loans made by the Banks because they involve a higher degree of credit risk. Equipment financing customers are typically small-business owners who operate with limited financial resources and who face greater risks when the economy weakens or unforeseen adverse events arise. Because of these characteristics, personal guarantees of borrowers are usually obtained along with liens on available assets. The size of loan is determined by an analysis of cash flow and other characteristics pertaining to the business and the equipment to be financed, based on detailed revenue and profitability data of similar operations.
Loans to condominium associations are for the purpose of funding capital improvements, are made for five- to ten-year terms and are secured by a general assignment of condominium association revenues. Among the factors considered in the underwriting of such loans are the level of owner occupancy, the financial condition and history of the condominium association, the attractiveness of the property in relation to the market in which it is located and the reasonableness of estimates of the cost of capital improvements to be made. Depending on loan size, funds are advanced as capital improvements are made and, in more complex situations, after completion of engineering inspections.
Consumer Loans
The consumer loan portfolio, which is composed of residential mortgage loans, home equity loans and lines of credit, and other consumer loans, represented 15.8% of total loans outstanding as of June 30, 2023. The Company focuses its mortgage and home equity lending on existing and new customers within its branch networks in its urban and suburban marketplaces in the greater Boston and Providence metropolitan areas.
The Company originates adjustable- and fixed-rate residential mortgage loans secured by one- to four-family residences. Each residential mortgage loan granted is subject to a satisfactorily completed application, employment verification, credit history and a demonstrated ability to repay the debt. Generally, loans are not made when the loan-to-value ratio exceeds 80% unless private mortgage insurance is obtained and/or there is a financially strong guarantor. Appraisals are performed by outside independent fee appraisers.
Underwriting guidelines for home equity loans and lines of credit are similar to those for residential mortgage loans. Home equity loans and lines of credit are limited to no more than 80% of the appraised value of the property securing the loan including the amount of any existing first mortgage liens.most critical accounting policies.

In March 2023, the FASB issued ASU 2023-02, "Investments – Equity Method and Joint Ventures (Topic 323), Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method" which allows entities to use the proportional amortization method to account for tax equity investments, under certain conditions. This ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years for public entities. Management has determined that ASU 2023-02 does apply to the Company and is currently determining the impact as of September 30, 2023.
Non-GAAP Financial Measures and Reconciliation to GAAP
In addition to evaluating the Company’s results of operations in accordance with GAAP, management periodically supplements this evaluation with an analysis of certain non-GAAP financial measures, such as operating earnings metrics, the return on average tangible assets, return on average tangible equity, the tangible equity ratio, tangible book value per share, and dividend payout ratio. Management believes that these non-GAAP financial measures provide information useful to investors in understanding the Company’s underlying operating performance and trends, and facilitates comparisons with the performance assessment of financial performance, including non-interest expense control, while the tangible equity ratio and tangible book value per share are used to analyze the relative strength of the Company’s capital position.

Net Income
For the three months ended September 30, 2023, the Company reported net income of $22.7 million, or $0.26 per basic and diluted share, a decrease of $7.4 million, or 24.7%, from net income of $30.1 million, or $0.39 per basic and diluted share, for the three months ended September 30, 2022. This decrease in net income is primarily the result of an increase in non-interest expense of $12.7 million, an increase in the provision for credit losses of $0.1 million, and a decrease in non-interest income of $1.3 million, partially offset by an increase in net interest income of $6.0 million and a decrease in the provision for income taxes of $0.8 million. Refer to “Results of Operations" below for further discussion.
For the nine months ended September 30, 2023, the Company reported net income of $52.1 million, or $0.59 per basic and diluted share, a decrease of $27.9 million, or 34.9%, from $80.0 million, or $1.04 per basic and diluted share for the nine months ended September 30, 2022.

Refer to “Results of Operations" below for further discussion.
The annualized return on average assets was 0.81% for the three months ended September 30, 2023, compared to 1.40% for the three months ended September 30, 2022. The annualized return on average stockholders' equity was 7.78% for the three months ended September 30, 2023, compared to 12.29% for the three months ended September 30, 2022.
The net interest margin was 3.18% for the three months ended September 30, 2023, down from 3.80% for the three months ended September 30, 2022. The decrease in the net interest margin is a result of an increase of 200 basis points in the Company's overall cost of funds (including non-interest-bearing demand checking accounts) to 2.57% for the three months ended September 30, 2023 from 0.57% for the three months ended September 30, 2022, partially offset by an increase in the yield on interest-earning assets of 126 basis points to 5.61% for the three months ended September 30, 2023 from 4.35% for the three months ended September 30, 2022.
The net interest margin was 3.27% for the nine months ended September 30, 2023, down from 3.62% for the nine months ended September 30, 2022. The decrease in the net interest margin is a result of an increase of 191 basis points in the Company's overall cost of funds (including non-interest-bearing demand checking accounts) to 2.31% for the nine months ended September 30, 2023 from 0.40% for the nine months ended September 30, 2022, partially offset by an increase in the yield on interest-earning assets of 143 basis points to 5.40% for the nine months ended September 30, 2023 from 3.97% for the nine months ended September 30, 2022.
The Company’s net interest margin and net interest income is sensitive to the structure and level of interest rates as well as competitive pricing in all loan and deposit categories.
Critical Accounting Policies and Estimates
The SEC defines “critical accounting policies” as those involving significant judgments and difficult or complex assumptions by management, often as a result of the need to make estimates about matters that are inherently uncertain or variable, which have, or could have, a material impact on the carrying value of certain assets or net income. The preparation of financial statements in accordance with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, income and expenses, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates. As discussed in the Company’s 2022 Annual Report on Form 10-K, management has identified the determination of the allowance for credit losses and the review of goodwill for impairment as the Company’s most critical accounting policies.

Recent Accounting Developments
In March 2023, the FASB issued ASU 2023-02, "Investments – Equity Method and Joint Ventures (Topic 323), Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method" which allows entities to use the proportional amortization method to account for tax equity investments, under certain conditions. This ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years for public entities. Management has determined that ASU 2023-02 does apply to the Company and is currently determining the impact as of September 30, 2023.
Non-GAAP Financial Measures and Reconciliation to GAAP
In addition to evaluating the Company’s results of operations in accordance with GAAP, management periodically supplements this evaluation with an analysis of certain non-GAAP financial measures, such as operating earnings metrics, the return on average tangible assets, return on average tangible equity, the tangible equity ratio, tangible book value per share, and dividend payout ratio. Management believes that these non-GAAP financial measures provide information useful to investors in understanding the Company’s underlying operating performance and trends, and facilitates comparisons with the performance assessment of financial performance, including non-interest expense control, while the tangible equity ratio and tangible book value per share are used to analyze the relative strength of the Company’s capital position.

The Company's loan portfolio consists primarily of first mortgage loans secured by commercial, multi-family and residential real estate properties located in the Company's primary lending area, loans to business entities, including commercial lines of credit, loans to condominium associations and loans and leases used to finance equipment used by small businesses. The Company also provides financing for construction and development projects, home equity and other consumer loans.
The Company employs seasoned commercial lenders and retail bankers who rely on community and business contacts as well as referrals from customers, attorneys and other professionals to generate loans and deposits. Existing borrowers are also an important source of business since many of them have more than one loan outstanding with the Company. The Company's ability to originate loans depends on the strength of the economy, trends in interest rates, and levels of customer demand and market competition.
The Company's current policy is that a total credit exposure to one obligor relationship may not exceed $60.0 million unless approved by the Company's Credit Committee. As of September 30, 2023, there were four borrowers with loans and commitments over $60.0 million. The total of those loans and commitments was $260.0 million, or 2.3% of total loans and commitments, as of September 30, 2023. As of December 31, 2022, there were three borrowers with loans and commitments

Table of Contents
over $60.0 million. The total of those loans and commitments was $208.5 million, or 2.2% of total loans and commitments, as of December 31, 2022.
The Company has written underwriting policies to control the inherent risks in loan origination. The policies address approval limits, loan-to-value ratios, appraisal requirements, debt service coverage ratios, loan concentration limits and other matters relevant to loan underwriting.
Commercial Real Estate Loans
The commercial real estate portfolio is composed of commercial real estate loans, multi-family mortgage loans, and construction loans and is the largest component of the Company's overall loan portfolio, representing 60.5% of total loans and leases outstanding as of September 30, 2023.
Typically, commercial real estate loans are larger in size and involve a greater degree of risk than owner-occupied residential mortgage loans. Loan repayment is usually dependent on the successful operation and management of the properties and the value of the properties securing the loans. Economic conditions can greatly affect cash flows and property values.
A number of factors are considered in originating commercial real estate and multi-family mortgage loans. The qualifications and financial condition of the borrower (including credit history), as well as the potential income generation and the value and condition of the underlying property, are evaluated. When evaluating the qualifications of the borrower, the Company considers the financial resources of the borrower, the borrower's experience in owning or managing similar property and the borrower's payment history with the Company and other financial institutions. Factors considered in evaluating the underlying property include the net operating income of the mortgaged premises before debt service and depreciation, the debt service coverage ratio (the ratio of cash flow before debt service to debt service), the use of conservative capitalization rates, and the ratio of the loan amount to the appraised value. Generally, personal guarantees are obtained from commercial real estate loan borrowers.
Commercial real estate and multi-family mortgage loans are typically originated for terms of five to fifteen years with amortization periods of 20 to 30 years. Many of the loans are priced at inception on a fixed-rate basis generally for periods ranging from two to five years with repricing periods for longer-term loans. When possible, prepayment penalties are included in loan covenants on these loans. For commercial customers who are interested in loans with terms longer than five years, the Company offers loan level derivatives to accommodate customer need.
The Company's urban and suburban market area is characterized by a large number of apartment buildings, condominiums and office buildings. As a result, commercial real estate and multi-family mortgage lending has been a significant part of the Company's activities for many years. These types of loans typically generate higher yields, but also involve greater credit risk. Many of the Company's borrowers have more than one multi-family or commercial real estate loan outstanding with the Company.
The Company's commercial real estate portfolio is composed primarily of loans secured by apartment buildings ($1.3 billion), office buildings ($849.9 million), retail stores ($953.9 million), industrial properties ($751.0 million), mixed-use properties ($508.0 million), lodging services ($195.3 million), and food services ($77.7 million) as of September 30, 2023. At that date, approximately 78.3% of the commercial real estate loans outstanding were secured by properties located in New England, and approximately 18.0% of the commercial real estate loans outstanding were secured by properties located in the greater New York and New Jersey Metropolitan area.
Construction and development financing is generally considered to involve a higher degree of risk than long-term financing on improved, occupied real estate and thus has lower concentration limits than do other commercial credit classes. Risk of loss on a construction loan is largely dependent upon the accuracy of the initial estimate of construction costs, the estimated time to sell or rent the completed property at an adequate price or rate of occupancy, and market conditions. If the estimates and projections prove to be inaccurate, the Company may be confronted with a project which, upon completion, has a value that is insufficient to assure full loan repayment.
Criteria applied in underwriting construction loans for which the primary source of repayment is the sale of the property are different from the criteria applied in underwriting construction loans for which the primary source of repayment is the stabilized cash flow from the completed project. For those loans where the primary source of repayment is from resale of the property, in addition to the normal credit analysis performed for other loans, the Company also analyzes project costs, the attractiveness of the property in relation to the market in which it is located and demand within the market area. For those construction loans where the source of repayment is the stabilized cash flow from the completed project, the Company analyzes not only project costs but also how long it might take to achieve satisfactory occupancy and the reasonableness of projected rental rates in relation to market rental rates.

Commercial Loans
The Company's commercial loan and lease portfolio is composed of commercial loans, equipment financing loans and leases and condominium association loans, which represented 23.9% of total loans outstanding as of September 30, 2023.
The Company's commercial loan and lease portfolio is composed primarily of loans and leases to small to medium sized businesses ($820.9 million), transportation services ($359.3 million), food services ($195.6 million), recreation services ($142.6 million), manufacturing ($110.6 million), retail ($149.9 million), and rental and leasing services ($59.4 million) as of September 30, 2023.
The Company provides commercial banking services to companies in its market area. Approximately 39.0% of the commercial loans outstanding as of September 30, 2023 were made to borrowers located in New England. The remaining 61.0% of the commercial loans outstanding were made to borrowers in other areas in the United States of America, primarily by the Company's equipment financing divisions. Product offerings include lines of credit, term loans, letters of credit, deposit services and cash management. These types of credit facilities have as their primary source of repayment cash flows from the operations of a business. Interest rates offered are available on a floating basis tied to the prime rate or a similar index or on a fixed-rate basis referenced on the FHLB of Boston and FHLB of New York index.
Credit extensions are made to established businesses on the basis of loan purpose and assessment of capacity to repay as determined by an analysis of their financial statements, the nature of collateral to secure the credit extension and, in most instances, the personal guarantee of the owner of the business as well as industry and general economic conditions. The Company also participates in U.S. Government programs such as the SBA 7A program and as an SBA preferred lender. Included in the commercial loans balances are the PPP loans totaling $0.3 million as of September 30, 2023.
The Company’s equipment financing divisions focus on market niches in which its lenders have deep experience and industry contacts, and on making loans to customers with business experience. An important part of the Company’s equipment financing loan origination volume comes from equipment manufacturers and existing customers as they expand their operations. The equipment financing portfolio is composed primarily of loans to finance laundry, tow trucks, fitness, dry cleaning and convenience store equipment. Approximately 17.3% of the commercial loans outstanding in the equipment financing divisions were made to borrowers located primarily in the greater New York and New Jersey metropolitan area. Typically, the loans are priced at a fixed rate of interest and require monthly payments over their 3- to 7-year life. The yields earned on equipment financing loans are higher than those earned on the commercial loans made by the Banks because they involve a higher degree of credit risk. Equipment financing customers are typically small-business owners who operate with limited financial resources and who face greater risks when the economy weakens or unforeseen adverse events arise. Because of these characteristics, personal guarantees of borrowers are usually obtained along with liens on available assets. The size of loan is determined by an analysis of cash flow and other characteristics pertaining to the business and the equipment to be financed, based on detailed revenue and profitability data of similar operations.
Loans to condominium associations are for the purpose of funding capital improvements, are made for five- to ten-year terms and are secured by a general assignment of condominium association revenues. Among the factors considered in the underwriting of such loans are the level of owner occupancy, the financial condition and history of the condominium association, the attractiveness of the property in relation to the market in which it is located and the reasonableness of estimates of the cost of capital improvements to be made. Depending on loan size, funds are advanced as capital improvements are made and, in more complex situations, after completion of engineering inspections.
Consumer Loans
The consumer loan portfolio, which is composed of residential mortgage loans, home equity loans and lines of credit, and other consumer loans, represented 15.6% of total loans outstanding as of September 30, 2023. The Company focuses its mortgage and home equity lending on existing and new customers within its branch networks in its urban and suburban marketplaces in the greater Boston, Lower Hudson Valley of New York, and Providence metropolitan areas.
The Company originates adjustable- and fixed-rate residential mortgage loans secured by one- to four-family residences. Each residential mortgage loan granted is subject to a satisfactorily completed application, employment verification, credit history and a demonstrated ability to repay the debt. Generally, loans are not made when the loan-to-value ratio exceeds 80% unless private mortgage insurance is obtained and/or there is a financially strong guarantor. Appraisals are performed by outside independent fee appraisers.
Underwriting guidelines for home equity loans and lines of credit are similar to those for residential mortgage loans. Home equity loans and lines of credit are limited to no more than 80% of the appraised value of the property securing the loan including the amount of any existing first mortgage liens.

Other consumer loans have historically been a modest part of the Company's loan originations. As of September 30, 2023, other consumer loans equaled $48.3 million, or 0.5% of total loans outstanding.
Asset Quality
Criticized and Classified Assets
The Company's management rates certain loans and leases as "other assets especially mentioned" ("OAEM"), "substandard" or "doubtful" based on criteria established under banking regulations. These loans and leases are collectively referred to as "criticized" assets. Loans and leases rated OAEM have potential weaknesses that deserve management's close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects of the loan or lease at some future date. Loans and leases rated as substandard are inadequately protected by the payment capacity of the obligor or of the collateral pledged, if any. Substandard loans and leases have a well-defined weakness or weaknesses that jeopardize the liquidation of debt and are characterized by the distinct possibility that the Company will sustain some loss if existing deficiencies are not corrected. Loans and leases rated as doubtful have well-defined weaknesses that jeopardize the orderly liquidation of debt and partial loss of principal is likely. As of JuneSeptember 30, 2023, the Company had $158.4$156.7 million of total assets that were designated as criticized. This compares to $108.2 million of assets designated as criticized as of December 31, 2022. The increase of $50.2$48.5 million in criticized assets was primarily driven by increases in commercial real estate and equipment financing relationships for the sixnine months ended JuneSeptember 30, 2023.
Nonperforming Assets
"Nonperforming assets" consist of nonaccrual loans and leases, other real estate owned ("OREO") and other repossessed assets. Under certain circumstances, the Company may restructure the terms of a loan or lease as a concession to a borrower, except for acquired loans and leases which are individually evaluated against expected performance on the date of acquisition. These restructured loans and leases are generally considered "nonperforming loans and leases" until a history of collection of at least six months on the restructured terms of the loan or lease has been established. OREO consists of real estate acquired through foreclosure proceedings and real estate acquired through acceptance of a deed in lieu of foreclosure. Other repossessed assets consist of assets that have been acquired through foreclosure that are not real estate and are included in other assets on the Company's unaudited consolidated balance sheets.
Accrual of interest on loans generally is discontinued when contractual payment of principal or interest becomes past due 90 days or, if in management's judgment, reasonable doubt exists as to the full timely collection of interest. When a loan is placed on nonaccrual status, interest accruals cease and all previously accrued and uncollected interest is reversed and charged against current interest income. Interest payments on nonaccrual loans are generally applied to principal. If collection of the principal is reasonably assured, interest payments are recognized as income on the cash basis. Loans are generally returned to accrual status when principal and interest payments are current, full collectability of principal and interest is reasonably assured and a consistent record of at least six months of performance has been achieved.
In cases where a borrower experiences financial difficulties and the Company makes or reasonably expects to make certain concessionary modifications to contractual terms, the loan is classified as a modified loan. In determining whether a debtor is experiencing financial difficulties, the Company considers, among other factors, if the debtor is in payment default or is likely to be in payment default in the foreseeable future without the modification, the debtor declared or is in the process of declaring bankruptcy, there is substantial doubt that the debtor will continue as a going concern, the debtor's entity-specific projected cash flows will not be sufficient to service its debt, or the debtor cannot obtain funds from sources other than the existing creditors at market terms for debt with similar risk characteristics.
As of JuneSeptember 30, 2023, the Company had nonperforming assets of $46.9$51.5 million, representing 0.42%0.46% of total assets, compared to nonperforming assets of $15.3 million, or 0.17% of total assets as of December 31, 2022. The increase of $31.6$36.2 million in nonperforming assets was primarily driven by the inclusion of loans related to one commercial customer totaling $9.3$22.7 million threeincrease in commercial real estate customers totaling $5.2loans, the $4.9 million increase in commercial loans, and two commercial real estate customers totaling $4.2the $4.3 million increase in equipment financing loans during the sixnine months ended JuneSeptember 30, 2023.
The Company evaluates the underlying collateral of each nonaccrual loan and lease and continues to pursue the collection of interest and principal. Management believes that the current level of nonperforming assets remains manageable relative to the size of the Company's loan and lease portfolio. If economic conditions were to worsen or if the marketplace were to experience prolonged economic stress, it is likely that the level of nonperforming assets would increase, as would the level of charged-off loans.

Allowance for Credit Losses
The allowance for credit losses consists of general and specific allowances and reflects management's estimate of expected loan and lease losses over the life of the loan or lease. Management uses a consistent and systematic process and methodology to evaluate the adequacy of the allowance for credit losses on a quarterly basis. Management continuously evaluates and challenges inputs and assumptions in the allowance for credit losses.
While management evaluates currently available information in establishing the allowance for credit losses, future adjustments to the allowance for loan and lease losses may be necessary if conditions differ substantially from the assumptions used in making the evaluations. Management performs a comprehensive review of the allowance for credit losses on a quarterly basis. In addition, various regulatory agencies, as an integral part of their examination process, periodically review a financial institution's allowance for credit losses and carrying amounts of other real estate owned. Such agencies may require the
6665

Table of Contents
financial institution to recognize additions or reductions to the allowance based on their judgments about information available to them at the time of their examination.
The Company’s allowance methodology provides a quantification of estimated losses in the portfolio. Under the current methodology, management estimates losses over the life of the loan using reasonable and supportable forecasts. Forecasts, loan data, and model documentation are extensively analyzed and reviewed throughout the quarter to ensure estimated losses are appropriate at quarter end.

The fair value of investment securities is based principally on market prices and dealer quotes received from third-party, nationally-recognized pricing services for identical investment securities such as U.S. Treasury and agency securities. The Company's marketable equity securities are priced this way and are included in Level 1 of the fair value hierarchy in accordance with ASC 820. These prices are validated by comparing the primary pricing source with an alternative pricing source when available. When quoted market prices for identical securities are unavailable, the Company uses market prices provided by independent pricing services based on recent trading activity and other observable information, including but not limited to market interest-rate curves, referenced credit spreads and estimated prepayment speeds where applicable. These investments include certain U.S. and government agency debt securities, municipal and corporate debt securities, GSE residential MBSs and CMOs, all of which are included in Level 2. Certain fair values are estimated using pricing models and are included in Level 3.

Additionally, management reviews changes in fair value from period to period and performs testing to ensure that prices received from the third parties are consistent with their expectation of the market. Changes in the prices obtained from the pricing service are analyzed from month to month, taking into consideration changes in market conditions including changes in mortgage spreads, changes in U.S. Treasury security yields and changes in generic pricing of 15-year and 30-year securities. Additional analysis may include a review of prices provided by other independent parties, a yield analysis, a review of average life changes using Bloomberg analytics and a review of historical pricing for the particular security.

Results of Operations
The primary drivers of the Company's net income are net interest income, which is strongly affected by the net yield on and growth of interest-earning assets and liabilities, the quality of the Company's assets, its levels of non-interest income and non-interest expense, and its tax provision.
The Company's net interest income represents the difference between interest income earned on its investments, loans and leases, and its cost of funds. Interest income is dependent on the amount of interest-earning assets outstanding during the period and the yield earned thereon. Cost of funds is a function of the average amount of deposits and borrowed money outstanding during the year and the interest rates paid thereon. The net interest margin is calculated by dividing net interest income by average interest-earning assets. Net interest spread is the difference between the average rate earned on interest-earning assets and the average rate paid on interest-bearing liabilities. The increases or decreases, as applicable, in the components of interest income and interest expense, expressed in terms of fluctuation in average volume and rate, are summarized under "Rate/Volume Analysis" below. Information as to the components of interest income, interest expense and average rates is provided under "Average Balances, Net Interest Income, Interest-Rate Spread and Net Interest Margin" below.
Because the Company's assets and liabilities are not identical in duration and in repricing dates, the differential between the two is vulnerable to changes in market interest rates as well as the overall shape of the yield curve. These vulnerabilities are inherent to the business of banking and are commonly referred to as "interest-rate risk." How interest-rate risk is measured and, once measured, how much interest-rate risk is taken on, are based on numerous assumptions and other subjective judgments. See the discussion in “Item 3. Quantitative and Qualitative Disclosures about Market Risk” below.
The quality of the Company's assets also influences its earnings. Loans and leases that are not paid on a timely basis and exhibit other weaknesses can result in the loss of principal and/or interest income. Additionally, the Company must make timely provisions to the allowance for loan and lease losses based on estimates of probable losses inherent in the loan and lease portfolio. These additions, which are charged against earnings, are necessarily greater when greater probable losses are expected. Further, the Company incurs expenses as a result of resolving troubled assets. These variables reflect the "credit risk" that the Company takes on in the ordinary course of business and are further discussed under "Financial Condition—Asset Quality" above.
Net Interest Income
Net interest income increased $14.2$6.0 million to $86.0$84.1 million for the three months ended JuneSeptember 30, 2023 from $71.9$78.0 million for the three months ended JuneSeptember 30, 2022. This increase reflects a $58.0$52.2 million increase in interest income on loans and leases, along with a $9.3$6.2 million increase in interest income on debt securities, short term investments and restricted equity securities, offset by a $53.2$52.4 million increase in interest expense on deposits and borrowings, which is reflective of the rising interest rate environment. Refer to “Results of Operations - Comparison of the Three-Month Period Ended JuneSeptember 30, 2023 and JuneSeptember 30, 2022 — Interest Income” and “Results of Operations - Comparison of the Three-Month Period Ended JuneSeptember 30, 2023 and JuneSeptember 30, 2022 — Interest Expense -Deposit and Borrowed Funds” below for more details.
Net interest income increased $30.4$36.4 million to $172.1$256.2 million for the sixnine months ended JuneSeptember 30, 2023 from $141.7$219.7 million for the sixnine months ended JuneSeptember 30, 2022. This overall increase reflects a $108.2$160.4 million increase in interest income on loans and leases and a $16.5$22.8 million increase in interest income on investments, offset by a $94.4$146.8 million increase in interest expense on deposit and borrowings, which is reflective of the rising interest rate environment.

Management seeks to position the balance sheet to be neutral to asset sensitive changes in interest rates. From 2017 through 2019, short term interest rates rose while at the same time net interest income, net interest spread, and net interest margin also increased. During 2020, interest rates declined sharply in response to the economic impact of the COVID-19 pandemic, and began to increase in the first quarter of 2022. In recent months, the Treasury yield curve has inverted and flattened at the long end. Short term rates have risen sharply due to multiple rate hikes implemented by the FRB. The shape of the curve indicates rates will begin to decline within a year and flatten around the 7-year mark. The short term increase in rates positively affected the Company's net interest income, net interest spread, and net interest margin initially. In the first sixnine months of 2023 and as expected in the near term, the net interest margin is expected to compress as deposit pricing "catches up" and investable funds migrate among depository and non-depository categories. Management expects this to persist for a quarter or two after the Federal Reserve stops increasing rates after which time net interest margin is expected to stabilize and then increase as loans continue to reprice into the higher rate environment.
Average Balances, Net Interest Income, Interest-Rate Spread and Net Interest Margin
The following table sets forth information about the Company's average balances, interest income and interest rates earned on average interest-earning assets, interest expense and interest rates paid on average interest-bearing liabilities, interest-rate spread and net interest margin for the three and sixnine months ended JuneSeptember 30, 2023 and JuneSeptember 30, 2022. Average balances are derived from daily average balances and yields include fees, costs and purchase-accounting-related premiums and discounts which are considered adjustments to coupon yields in accordance with GAAP.

The following table presents, on a tax-equivalent basis, the extent to which changes in interest rates and changes in volume of interest-earning assets and interest-bearing liabilities have affected the Company's interest income and interest expense during the periods indicated. Information is provided in each category with respect to: (i) changes attributable to changes in volume (changes in volume multiplied by prior rate), (ii) changes attributable to changes in rate (changes in rate multiplied by prior volume), and (iii) the net change. The changes attributable to the combined impact of volume and rate have been allocated proportionately to the changes due to volume and the changes due to rate.

Item 3. Quantitative and Qualitative Disclosures about Market Risk
Market Risk
Market risk is the risk that the market value or estimated fair value of the Company's assets, liabilities, and derivative financial instruments will decline as a result of changes in interest rates or financial market volatility, or that the Company's net income will be significantly reduced by interest-rate changes.
Interest-Rate Risk
The principal market risk facing the Company is interest-rate risk, which can occur in a variety of forms, including repricing risk, yield-curve risk, basis risk, and prepayment risk. Repricing risk occurs when the change in the average yield of either interest-earning assets or interest-bearing liabilities is more sensitive than the other to changes in market interest rates. Such a change in sensitivity could reflect a number of possible mismatches in the repricing opportunities of the Company's assets and liabilities. Yield-curve risk reflects the possibility that changes in the shape of the yield curve could have different effects on the Company's assets and liabilities. Basis risk occurs when different parts of the balance sheet are subject to varying base rates reflecting the possibility that the spread from those base rates will deviate. Prepayment risk is associated with financial instruments with an option to prepay before the stated maturity, often a disadvantage to person selling the option; this risk is most often associated with the prepayment of loans, callable investments, and callable borrowings.
Asset/Liability Management
Market risk and interest-rate risk management is governed by the Company's Asset/Liability Committee ("ALCO").ALCO. The ALCO establishes exposure limits that define the Company's tolerance for interest-rate risk. The ALCO and the Company's Treasury Group measure and manage the composition of the balance sheet over a range of possible changes in interest rates while remaining responsive to market demand for loan and deposit products. The ALCO monitors current exposures versus limits and reports those results to the Board of Directors. The policy limits and guidelines serve as benchmarks for measuring interest-rate risk and for providing a framework for evaluation and interest-rate risk-management decision-making. The Company measures its interest-rate risk by using an asset/liability simulation model. The model considers several factors to determine the Company's potential exposure to interest-rate risk, including measurement of repricing gaps, duration, convexity, value-at-risk, market value of portfolio equity under assumed changes in the level of interest rates, the shape of yield curves, and general market volatility.
Management controls the Company's interest-rate exposure using several strategies, which include adjusting the maturities of securities in the Company's investment portfolio, limiting or expanding the terms of loans originated, limiting fixed-rate deposits with terms of more than five years, and adjusting maturities of FHLB advances. The Company limits this risk by restricting the types of MBSs it invests into those with limited average life changes under certain interest-rate-shock scenarios, or securities with embedded prepayment penalties. The Company also places limits on holdings of fixed-rate mortgage loans with maturities greater than five years. The Company enters into interest rate swaps as part of its interest rate risk management strategy. These interest rate swaps are designated as cash flow hedges and involve the receipt of variable rate amounts from a counterparty in exchange for the Company making fixed payments.
Measuring Interest-Rate Risk
As noted above, interest-rate risk can be measured by analyzing the extent to which the repricing of assets and liabilities are mismatched to create an interest-rate sensitivity gap. An asset or liability is said to be interest-rate sensitive within a specific period if it will mature or reprice within that period. The interest-rate sensitivity gap is defined as the difference between the amount of interest-earning assets maturing or repricing within a specific time period and the amount of interest-bearing liabilities maturing or repricing within that same time period. A gap is considered positive when the amount of interest-rate-sensitive assets exceeds the amount of interest-rate-sensitive liabilities. A gap is considered negative when the amount of interest-rate-sensitive liabilities exceeds the amount of interest-rate-sensitive assets. During a period of falling interest rates, therefore, a positive gap would tend to adversely affect net interest income. Conversely, during a period of rising interest rates, a positive gap position would tend to result in an increase in net interest income.
The Company's interest-rate risk position is measured using both income simulation and interest-rate sensitivity "gap" analysis. Income simulation is the primary tool for measuring the interest-rate risk inherent in the Company's balance sheet at a given point in time by showing the effect on net interest income, over a twelve-month period, of a variety of interest-rate shocks. These simulations take into account repricing, maturity, and prepayment characteristics of individual products. The ALCO reviews simulation results to determine whether exposure resulting from changes in market interest rates remains within established tolerance levels over a twelve-month horizon, and develops appropriate strategies to manage this exposure. The Company's interest-rate risk analysis remains modestly asset-sensitive as of JuneSeptember 30, 2023.

The assumptions used in the Company’s interest-rate sensitivity simulation discussed above are inherently uncertain and, as a result, the simulations cannot precisely measure net interest income or precisely predict the impact of changes in interest rates.
As of JuneSeptember 30, 2023, net interest income simulation indicated that the Company's exposure to changing interest rates was within tolerance. The ALCO reviews the methodology utilized for calculating interest-rate risk exposure and may periodically adopt modifications to this methodology. The following table presents the estimated impact of interest-rate changes on the Company's estimated net interest income over the twelve-month periods indicated while maintaining a flat balance sheet:

The estimated impact of a 300 basis point increase in market interest rates on the Company's estimated net interest income over a twelve-month horizon was 5.4%2.4% as of JuneSeptember 30, 2023, compared to 7.4% as of December 31, 2022.
The Company also uses interest-rate sensitivity “gap” analysis to provide a more general overview of its interest-rate risk profile. The interest-rate sensitivity gap is defined as the difference between interest-earning assets and interest-bearing liabilities maturing or repricing within a given time period. At JuneSeptember 30, 2023, the Company’s one-year cumulative gap was a negative $205.0$673.1 million, or 1.97%6.48% of total interest-earning assets, compared with a positive $9.3 million, or 0.11% of total interest-earning assets, at December 31, 2022.
The assumptions used in the Company's interest-rate sensitivity simulation discussed above are inherently uncertain and, as a result, the simulations cannot precisely measure net interest income or precisely predict the impact of changes in interest rates. For additional discussion on interest-rate risk see Item 7A, “Quantitative and Qualitative Disclosures about Market Risk” of the Company’s 2022 Annual Report on Form 10-K.
Economic Value of Equity ("EVE") at Risk Simulation is conducted in tandem with net interest income simulations to ascertain a longer term view of the Company’s interest-rate risk position by capturing longer-term repricing risk and options risk embedded in the balance sheet. It measures the sensitivity of the economic value of equity to changes in interest rates. The EVE at Risk Simulation values only the current balance sheet and does not incorporate growth assumptions. As with the net interest income simulation, this simulation captures product characteristics such as loan resets, repricing terms, maturity dates, and rate caps and floors. Key assumptions include loan prepayment speeds, deposit pricing elasticity, and non-maturity deposit attrition rates. These assumptions can have significant impacts on valuation results as the assumptions remain in effect for the entire life of each asset and liability. The Company conducts non-maturity deposit behavior studies on a periodic basis to support deposit assumptions used in the valuation process. All key assumptions are subject to a periodic review.
EVE at Risk is calculated by estimating the net present value of all future cash flows from existing assets and liabilities using current interest rates as well as parallel shocks to the current interest-rate environment. The following table sets forth the estimated percentage change in the Company’s EVE at Risk, assuming various shifts in interest rates.

The Company's EVE-at-risk asset sensitivity decreased from December 31, 2022 to JuneSeptember 30, 2023 due to wholesale funding balances, as well as a more inverted yield curve.
